How much data does MSFS 2024 use, and how can I reduce it?
Microsoft Flight Simulator 2024 (MSFS 2024) has no fixed hourly data figure: use varies with flight length, streamed scenery, altitude, photogrammetry, live services and cache hits. An online session can consume hundreds of megabytes to several gigabytes, while major updates may use far more. Disable photogrammetry and world streaming first.
How much data per hour does MSFS 2024 use?
There is no dependable single per-hour rate for MSFS 2024. A representative one-hour online flight may use anything from hundreds of megabytes to several gigabytes, but low-level urban flying can exceed the amount used by a high-altitude flight over sparse terrain.
| Flight or activity | Practical expectation | Main reason |
|---|---|---|
| Online features mostly disabled | Minimal in-flight transfer, but not necessarily zero | Sign-in, licence and service checks may still use the connection |
| High-altitude IFR with photogrammetry off | Usually towards the lower end of the range | Less detailed nearby scenery must be fetched |
| Ordinary flight with online scenery and live services | Hundreds of megabytes to several gigabytes per hour is a sensible planning range | Scenery streams continuously as the aircraft moves |
| Low-level VFR or helicopter flight over a detailed city | Several gigabytes in an hour is possible | Dense terrain, imagery and 3D city data are loaded rapidly |
| Simulator or content update | May exceed several normal flights | Large packages are downloaded in one operation |
These are budgeting ranges, not benchmarks. Route, flight duration, server conditions, the amount already cached and the content installed locally can all change the result.
Connection speed and total data usage are different problems. Insufficient speed causes blurry terrain, late-loading objects and pauses; a monthly cap concerns the accumulated number of gigabytes transferred.
What uses the most data in Microsoft Flight Simulator 2024?
Streamed world scenery is normally the largest source of continuous data use. MSFS 2024 also delivers more simulator content from the cloud than its predecessor, so first loading an aircraft, airport or area may require additional transfers.
- World imagery and terrain: the core stream used while moving across the map, especially during low-level flight.
- Photogrammetry: detailed 3D city geometry that can substantially increase downloads over supported urban areas.
- Cloud-delivered simulator content: assets not already held locally may be fetched when needed.
- Live weather, traffic and multiplayer: recurring background data, usually secondary to scenery streaming.
- Simulator, world and optional-content updates: separate from flying, but often the largest one-off downloads.
Turning off photogrammetry does not stop all scenery downloads. It removes the detailed 3D city layer, while world imagery and terrain can continue streaming unless online world data is also reduced or disabled.
How do I reduce MSFS 2024 data usage on a capped connection?
The biggest savings come from controlling world streaming, then reusing cached scenery and disabling live services you do not need.
- Set a data allowance where available. If your version exposes a data-limitation control, set it below the provider's monthly allowance to leave room for updates and other devices. A bandwidth limit may reduce the transfer rate or scenery quality, but it is not necessarily a hard monthly cap.
- Turn off photogrammetry first. Choose this compromise when you want online terrain and imagery but can accept simpler city buildings. It is often the least disruptive high-impact change.
- Reduce or disable online world data. Use this when staying below the cap matters more than scenery fidelity. This provides a larger saving than lowering ordinary graphics settings, but the visual downgrade is greater.
- Keep the rolling cache enabled for repeated areas. Circuits at the same airport and regular flights around one city can reuse downloaded scenery instead of fetching it again.
- Use preset weather and disable live traffic or multiplayer. These changes produce smaller savings than reducing scenery streaming, but they are useful for training flights and repeated procedures.
- Avoid low-level urban sightseeing when the allowance is tight. High-altitude routes, open water and sparsely detailed regions generally require less scenery data than helicopter or VFR flights through photogrammetry cities.
- Schedule updates on an uncapped connection. Check the simulator, platform and optional-content library before using a hotspot. A queued update can consume more data than the flight itself.
- Measure one representative flight. Record network usage through the router, operating system or console, close unrelated downloads, fly for one hour on a typical route, then compare the total. Repeat with photogrammetry disabled to see the saving on your own setup.
Does rolling cache reduce data usage?
Yes, rolling cache reduces repeat downloads when you revisit the same scenery. It does not save data on the first visit, and a cache that is too small may evict older areas before you return to them.
Do not clear the cache as routine maintenance. Doing so forces MSFS 2024 to download those areas again. Clear or disable it only when troubleshooting corrupted scenery, persistent streaming faults or instability; our MSFS 2024 crash and rolling-cache troubleshooting steps explain when that is appropriate.
The rolling cache consumes drive capacity rather than internet allowance once the data has been stored. For the separate disk-space calculation, see our breakdown of how streamed scenery, cache, updates and add-ons affect MSFS storage.
Which settings do not reliably cut data use?
Lowering screen resolution, texture quality or the general graphics preset mainly reduces GPU, memory or CPU load. It is not a dependable way to control network usage because online world data may still be streamed.
A bandwidth limit is also different from a total-data limit. It can restrain the instantaneous download rate, but a long flight may still accumulate substantial usage. Deleting cached data is actively counterproductive when you repeatedly fly the same routes.
Can MSFS 2024 run on a hotspot or without internet?
A stable hotspot can run MSFS 2024, but fully online flying can exhaust a mobile allowance quickly. Use the simulator's data controls, disable heavy world streaming, prevent unrelated background downloads and verify that no simulator update is waiting before connecting.
MSFS 2024 is designed around cloud-delivered content and should not be treated as a fully offline simulator. With online features unavailable, scenery quality and functionality are reduced, live services disappear, and authentication or content checks may still require a connection.
